Examples

The following example creates an StylusPointDescription object from a StylusPointCollection and gets the information for each StylusPointPropertyInfo in the StylusPointDescription.

private void WriteDescriptionInfo(StylusPointCollection points)
{
    StylusPointDescription pointsDescription = points.Description;
    ReadOnlyCollection<StylusPointPropertyInfo> properties = 
        pointsDescription.GetStylusPointProperties();

    StringWriter descriptionStringWriter = new StringWriter();
    descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString());
    
    foreach (StylusPointPropertyInfo property in properties)
    {
        // GetStylusPointPropertyName is defined below and returns the
        // name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(property).ToString());
        descriptionStringWriter.WriteLine("  Guid = {0}", property.Id.ToString());
        descriptionStringWriter.Write("  IsButton = {0}", property.IsButton.ToString());
        descriptionStringWriter.Write("  Min = {0}", property.Minimum.ToString());
        descriptionStringWriter.Write("  Max = {0}", property.Maximum.ToString());
        descriptionStringWriter.Write("  Unit = {0}", property.Unit.ToString());
        descriptionStringWriter.WriteLine("  Res {0}", property.Resolution.ToString());
    }

    descriptionOutput.Text = descriptionStringWriter.ToString();
}
Private Sub WriteDescriptionInfo(ByVal points As StylusPointCollection) 

    Dim pointsDescription As StylusPointDescription = points.Description

    Dim properties As ReadOnlyCollection(Of StylusPointPropertyInfo) = _

        descriptionStringWriter.WriteLine("  Guid = {0}", pointProperty.Id.ToString())
        descriptionStringWriter.Write("  IsButton = {0}", pointProperty.IsButton.ToString())
        descriptionStringWriter.Write("  Min = {0}", pointProperty.Minimum.ToString())

    // that matches currentProperty, then return the name.

Remarks

The StylusPointPropertyInfo class inherits from the StylusPointProperty class and generates the Minimum, Maximum, Resolution, and Unit values used to define the properties of a StylusPoint. The validity of each property value varies depending on the manufacture of the digitizer and stylus.
